To all 'zrizcm 'nmy owz cer' n:

Be it known that 1, Fin-in lifnrnn, e citizen of the United fit-ates, aresident of lehiu, in the county of lazewell and State of Illinois, haveinvented new and useful 11n- PTOVEDIGDM in Door ()pening and ClosingDevices, of which. the following is a specification. I

This invention has inc; and closing dcvi and has for its prh 'pel objectto provide as'ini pens. re and yeteffecti've device of this characterapplicable ',ularly to doors, and including 31192118 for operating sucha device within the garage, or at a suitaliile point removed therefrom;whereby, when approaching the garage the driver of an automobile mayopen the garage doors without alighting; from the car. i

The invention has for a further object, spring means to assist in movingt e doors to open and also closed position, re predetermined novenientof the operating means, and also 1116)? s for holding the doors in openposition accidental closing, due to wind pressure.

That the invention may be more fully understood. reference is had to theaccompanying drawings forming a part of the present des irtion,illustrating a preferred embodi menu of the invention, in which:

1 a top plan view of my 1111- door opening and closing device applied togarage doors, the gar-ago being shown in dotted lines in adiagraini'natic way, with the garage doors in full lines, closet lio'ure 2 is a view except that the doors and the door opening: openposition, and 7 Fi nre 3 is av detail of parts of thedevice, as the somewould appear, if taken on the line 3-3 Figure 2.

Like characters of reference denote corresponding parts throughout thefigures.

In providing a. door opening and closing device for a garage, or similarbuilding, it will be understood that the door operating means must be solocated that an automobile, car or truck moving into and out of thebuilding will not encounter such device, or interfere with it, or beinterfered with, and therefore, evoen though 1 have elected .erencetodoor openc more 1:) roves:

similar to Figure 1, are in open position device also moved to to showthedevice in'nnediately beneath the ceiling of the building and withinthe interior of the building, it could conveniently be located in a coinzartinent below the floor ofthc building and be operated with as goodresults. And while Ihave shown the garage as having two hinged doors-theOll'liSSlGD of parts will enable it to be connected to one door andoperated with as good results.

'Yl A, being preferably shown in dotted lines, except the two doors,13,13 hinged thereto and adapted to be swung toward and from each other.A. supporting beam C is shown to which are connected certain operativeparts of the device.

1, 1, designate similar connecting barf; which have a suitable pivotalconnection, at

'2, with the doors B, and normally converge to a meeting point and havea pivotal con= nection with a control rod?) chnnected to ing point ofthe bars 1, when in closed, as well as when in open position,-controlled by the rod '3, is at a point on an imaginary line passingthrough the center of the garage and intersecting the meeting edges ofthe doors B, see Figures 1 and 2.

In practice the meeting ends of the bars,

1. lie garage or otherbuilding is designated swing freely from the beamC. The meet? connection with the beam C, and the latter to provide forthe connection of the bars 1, 1, therewith, and also a link 6 and a rod7 forming a connection for a coil spring 8,

the rod 9 from the opposite end, of which,

has a pivotal connection with the beam C.

To the beam C, and to one side of the dev ce, is journaled a-pulleywheel 10, over which is guided a rope or cable 11, the inner end ofwhich is connected to the link 6 and the forward portion of said rope orcable leads to one side of the garage, just inside the door, and passesover one or more guide pulleys l2 and 13, with a section, not shown,depending within reaching distance inside the garage, and the section 11passing out through the wall of the garage and led to a point in advancethereof where it passes a pull on the rope or cable 11 will move.

the bars 1 outwardly,.their inner pivotally connected ends swinging anan are of a circle described by the outer end ot the control rod 3swinging on its pivot on the beam C, and due to .such movement the doorsB are started nroving to open position. At the same time the pull isagainst the tension of the spring 8 which expands, until it is swungacross the pivot of the rod 8, with the beam C. il hen said springcontract-s, pulling the connected ends of the bars 1 and the end of thecontrol rod 3 into the position shown in Figure 2, resulting in thedoors'B being forced to the full open position shown in said Figure 2,and held in such position and prevented from closing due to windpressure.

To close the doors l3,a corresponding pull on the rope or cable 11 willcause the control rod 3 to retraverse its path of travel, drawing thebars 1 inwardly and swinging their inner ends in an arc of .acircledescribed by the movement of the outer end of the control rod 3,.agai'nexpanding the spring 8, which, assoon as it crosses the pivot point ofthe rodS with the beam C will contract, )ulling the connected ends ofthe bars 1 and the end of the control rod 3 into the position shown" inFigure 1, re sulting in the doors B being closed, as shown in saidFigure 1, and held in such closed position. I

- It is obvious that the location of the rope or cable and controlrodand spring may be initially placed at either side of thebuildingandcoperate with as good results. It is also obvious 'that if only oneooor is used, one of the bars 1 could be omitted, andthe device usedwith equally as good results.

Thedevice is simple, inexpensive, effective and may be convenientlyapplied and operated by an unskilled person or child. The slightest pullwill position the parts so that the full opening orclosing of the doorswill have the assistance of the spring 8, as will be understood.

iVhat I claim is In a door opening and closing device, in combination, apivotal control member, a pair of bars, each connected to a dool andconverging to andconnected with the swingable end of said member, a ropeor .cableconnected to the swingable end of said member and guided by apulley located at one side of said bars, and a spring for positioningsaid n'ieinber,-whereby its outer end and the connected ends of saidbars will intersect an imaginary line at their two ex- 'treme movements,said spring adapted to enpand through a partial swing of said member andto contract through the remainder of the swing of said member, when saidmember is swung either forward or back.

In witness whereof, I have hereunto aiiixed my hand ruary, 1923. 1
